Direct Catalytic Hydrothermal Liquefaction Of Spirulina To Biofuels With Hydrogen

We report herein on acquiring biofuels from direct catalytic hydrothermal liquefaction of spirulina. The component of bio-oil from direct catalytic hydrothermal liquefaction was similar to that from two independent processes (including liquefaction and upgrading of biocrude). However, one step process has higher carbon recovery, due to the less loss of carbons. It was demonstrated that the yield and HEW of bio-oil from direct catalytic algae with hydrothermal condition is higher than that from two independent processes.
